We have ben keeping an eye on this pair of Wood Pigeons raising one chick between them. They change shifts every 12 hours. The chick is now possibly as large as it parents but is not independent yet. It still relies on milk from both parents. It's beak is not hard enough yet to be able to eat seeds.
This is a parent woodpigeon of the nest we have perched very precariously on top of our hedge. I just managed to see the one chick today, and it looks almost completely feathered. It won't be long before it starts to fly away, and then it'll just be gone for good, I assume.
